What pep-talk? He's more of the "This violence is pointless. Please. Stop it; I don't wanna have to fight you." type.

He's actually had a "Dark Side" experience himself, ever since I canon-updated him some months ago. Cold, sadistic, torturous violence kind of dark side. So he's even felt it, and will try some understanding. That will ultimately fail and he'll have to whip out a lot of power just to survive.

That's all I've got for now. Whenever you've got more details, fire away!
